Sodium sulfate / ?magnesium sulfate / potassium chloride + Zoledronic acid

MediHelp rates the interaction as moderate. Sodium sulfate / ?magnesium sulfate / potassium chloride and Zoledronic acid can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken. Bowel-preparation solutions can cause dehydration and electrolyte shifts. Zoledronic acid lowers serum calcium and is nephrotoxic in volume-depleted patients, so combined exposure may add to the risk of hypocalcemia, arrhythmia, seizures and renal impairment.

MediHelp rates it moderate, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Ensure adequate hydration and correct baseline calcium and electrolyte abnormalities before bowel preparation. Check electrolytes and renal function in high-risk patients, and avoid infusing zoledronic acid during bowel preparation.

MediHelp also lists interactions of Zoledronic acid with, for example, Amikacin, Bumetanide, Dichlorphenamide. The full list is on the Zoledronic acid page.
